To all whom it may concern: 7 r p I Be it known that -I,:1IENRY E. Ross,- a citizen of the United States, residing at Mil- State of Wisconsin, have 'invented certain .IRDDI'OVGIDGill'S in) Lasting Machines, of which the following description, in connection with theaccoinpanying drawings, is'ja specification, like reference characters on the drawings figures. V This inv'entionrelates to lasting machines, and more particularly to end-lasting mech- 'in such as utilized, for example, in lasting the toes of shoes. The invention is here in illustrated in its application to a bed last ing machine of the same general type as that shown and described in'United- States Let? tels Patent No. 1,284,8'Z0 granted onfNo 12, 1918, upon an application of Matthias Brock, although the invention in wiarions novel aspects is'not limited to that particnlartype; I e I, It is a Well-known facttliat, asshoes that are made onsoc alled crooked lasts are pomacliines of sitioned in machines of thezibove-mentioned f type, the oppositesi'de faces of theme fpoie tion of each last are' bot-h inclined toward the front or toward the rear of the machine,

that is, toward or away from the operator, i

the direction of the incline depending upon Whether the shoe' is a right shoe or a left shoe. In order that the toe-embracing wipers in their upward or upi'viping n'oveinent shall hearwltli effective pressure upon the ,upper at bothsides of the toe, and in order that theWipers at'the end of the upwip'ing operation shall'h'e positioned with theinwiping' edges in proper relation to thefed'ge of the SllOB'bOttOIfl to begin the 'overwiping" operation, Ina-chines such as shown "in the above-mentioned patent iiicliid'e n ani ally 7 adjustable controlling mechanism acting an} toniatically in the upwiping operationto impart to the toe Wipers a predetefinine d inov'enient laterally. of the shoe relatively to'tl'iei'r" vertically inoving supp0rt-, so that the,ir up"- wiping movement is actually on an incline.

controlling mechanism shown in Fig. 5., and Figs. 8 and 9 are views showing in greater detail-a portion of the mechanism shown in Fig. 5 as viewed from opposite sides respectively. As more fully shown and described in the prior patents mentioned, the machine is provided with shoe-positioning means comprising a heel pin 2 which engages the last i in its spindle hole and a toe rest-4 upon which the forepart of the shoe is supported.- For operating upon the heel end of the shoe there is, provided heel-lasting; mechanism, comprising the usual heel band and wipers 6 i mounted on a heel carriage 8 which carries also the heel pin'2 and is pivoted to swing;

laterally about a vertical axis 10, thecarriage .8 being supported for swinging movement u'pon a track 12 by means of rolls let. In, operating upon shoesmade on-crooked I laststhe operator swings the heel carriage 8 in one direction to position it for operating uponlal right shoe and in thefopposite'direction to position it foroperating upon a left shoe. To insure that the heel-lasting mechanisnn in operating upon right and left shoes 7 respectively, will be positioned at equal distion the machine is provided with a pair of tances from a'central or intermediate posistops 16 which. are adjustable toward and .from each other by means of a rightand left screw. 18 and the heel carriage 8 has a latch 2O for engaging these stops to limitthe movement of the'carriage in the diifcrent directions. By-turning'thescrew 18 the operatorimay determine the angular relation of the heel-lasting mechanism to the longitudif nal median line .of the machine. which will be the same whether the mechanism is positioned for operating upon aright shoe or upon a left shoe. In the machine shown in Fig.1 the stops 16 are set'to position the l'ieel-lasting mechanism centrally foroperating' upon right or left shoes that are made on straight lasts.

The toe-lasting mechanism comprises toeembracing wipers. 22 and also, as herein shown, a toe band 24, although the invention is not limited to aconstruction includ ing a toe band. 'lhe wipers and the toe band are movable upwardly and downwardly by means of a vertically movable support 26 (Fig. 2) which is operated by atrcadle 28 (Fig. 1), and it will be understood thatby means of the treadle the operator raises the w pers 22 while holding them closed about the toe of the shoe by means of a hand lever ill;

30 to upwipe the upper aboutthe toe. The

wipers 22 and the toe band 2 are carried by a slide 82 which is mounted on the support 26 for movement laterally of theshoe. The slide 82 is provided at the rear with lu -see (Fig. 3) which have bearings for a cylindrical sleeve 36 and'haveopenings below the sleeve. The sleeve 36 is provided with a rectangular slot extending lengthwise thereof to receive a normally stationary square shaft 38, and secured to the sleeve between the lugs 34 is a block iilwhich is provided with a slot l2 n line with the slot in the sleeve to serve as a downwardextension of the latter.

The square shaft 38 is mounted at its ends in bearings so that it may be turned to position it with its opposite sides eltlll vertical or at any desired inclination to the vertical, the sleev-e36 and the block/l0 turning withthe shaft. It will thus be evident that if theshaft 38 18 positioned with its opposite sides vertical, no'moveni'ent laterally of the shoe-will be imparted to the slide32'and the toe wipers when the wiper support 26 is moved upwardly, but if the shaft is turned so that its opposite sides are at an inclination to the vertical, a proportional movement laterally of the shoe will be imparted to the thelaterally movable heel carriage 8, and

for this purpose the shaft 38 is connected -to the heel carriage. Fast on the shaft 38 is a slotted lever arm 4:4; which is connected to a similarly slotted arm of a lever 46, this lever having operative connection at its lower end with a pin 48 on one arm of a horizontal lever 50, and the latter being-con nected by means of a link 52 to the heel carriage v8 through mechanism hereinafter described. The connection between the arm:

44- and the lever 426 comprises a block 54 which is adjustable along the slot in the arm 7 4A: and has pivoted thereon a second block 56 which is movable along the slot in the lever arm 46; By this mechanism the shaft 38 is adjusted initially so that its opposite sides are vertical when the heel carriage 8 occupies va central position, thus insuring] that the toe Wipers will have lateral movements' of equal extent 'in operating u'pon' right and left shoes when the-heel carriage is moved to positions at equal distances fronr its central position. I

For purposes "of the present invention there is provided means for operating the horizontal lever to position the shaft 38 with its opposite sides at an inclination to the vertical when the heel'carria'g'e or the heel-lasting mechanism is in its intermediate or central position, and thusto cause the- ,toe Wipers to receive movement laterally of the shoe in pperating upon shoes made on straight lasts, without interfering with the normal use of the machine asv hereinbefore' described-in operating-upon shoes madeon crooked lasts. To this end, the connection between the link 52 and the heel carriage 8 central position. pending therefroma bracket 'in' which is a curved guideway; 62 for the slide 58,

the latter being provided on one side "with lugs 6a which support the slide at that side upon the top edge-of the bracket infany" position of the slider. Under the guideway 62 the bracket 60 is provided with a pair:

of straight guideways 66 inangular' relaguideways 66 are slides 68 which are a justable toward or from eachother by'means of right and left thre'aded'screws 70 which are connected together by auniversal joint 7 2 so that both are operated by turning. one, of them. The screws 70, are journaled at their'outer ends in bearings formed in the bracket 60, and one otthemis provided at 'madeon crockedlasts, the slides 68 are so adjusted that the pins 7 6* hold the slide 58" between them in a centralpos'ition on the heel carriage, as illustrated in Figs. 5, 6 and 7, so that the link 52 is.connect ed to the heel carriage at a-po-int substantially midway between the'oppositefsides of the latter,

as in the prior Brock machine of Patent No. 1,390,755. 7

When the inachinejtis to operate-upon shoes made on straight lasts, with'the heel reach it at all'tim'es I the slide 58 be lockedat either limitfoi. its

carriafge' 8 in a central position, as illus trated V-m Flg. 1, the slides 68 are so ada justed as topermit such movement of the slide 58 between the pins 7 6 as isnecessary in order to adjust the square shaft 38 to im part to the 'toefwipers the proper extent of lateral movement in operating on right,

swing about the. same axis 10- as the heel 7 carriage and is provided with a handle SOin a: convenient positionfor. the operator to It is desirable that movement'be'tweenthe pins 7 6, and for this purpose the slide has pivoted thereon a pair of latches 82 arranged to engage the respec tive, pins and pulled downwardly toward the pins by springs 84;. wFOrcontrolling these latches there is-mounted on the slide 58-, on the same pivot pinto which the link 52.is connected, a 'sleeve'86-having recesses i in 'itsopp'osite sides, as'showninjFigs;

andft); and in these recesses the sleeve is provided'K-vith downwardly facing cams 88 1 and 90. Extendinglfroan the latch 82 which is nearest the front of the machine is a curved arm 92- the endof which projects into oneotthe recesses in the'sleeve 86jand is erigagedbythe cam 88. Extending ,froin the other latch 82 is a-n'arm Qiwhichhas onits' turned in one direction from-its intermediate position, releases one ofjthe latches 82 to permlt I it i to engage the corresponding pm I end a lateral projection 96 engaged by b11612 can ;90. The cams 88 and 90" are so are: ranged that when the sleeve 86 is inan intermediate position bf oththe latches 82a'ref held outof engagement withthe pins "16, as i.1- lustrated in Fig. 7. When the sleeve 86 is tion to each other, and mounted in the T 6, while continuing to hold the other latch upwardly outof positionito engage its pin,"

When the sleeve is turned in :the oppositedigrection it releases the last-named latch, while holding the first one in an elevated position. Movement of thefsl'eeve' "86 infone di it i I.

no I

reetion is limited by engagement of a.

shoulder 98thereon with the end ofthe arm 92, and movemento'f" the sleeve' in-the opposite direction is limitedl'by engagement of a shoulder 100 thereon with'the projec- I tion 96 on the arm'9'at; The sleeve 86 is controlled by the lever; 7 8 which, for this purpose, is. connected to a crank. arm I102 projectingfromthesleeve:' i

When the machine is tooperate upon shoes *thatiare made on straightjlasts the heel carriage; 8 is latched in central posi "tion, as shown in Fig; 1. If the shape of I the last makes it-desirable to impart lateral movementito thetoe wipers in the upwiping operation, the operator adjusts the slides 68 far enough apart to permit such movement on" the sleeve en 'a es the end of the armto D of the slide 58 and the connected parts of the u-*i1t )er-controlling mechanism as is necessary to give the Wipers the lateral movement required. The adjustment for any particular style of shoe may be conveniently determined by trial. 'lo position the parts for operating upon a left shoe, as illustrated, the operator swings the lever 78 forwardly until the slide 58 engages that pin 76 which is nearest the front of the machine. In this movement of the lever 78 the sleeve 86 is first turned so as to release the latch 82 which is nearest the front of the machine, while maintaining the other latch in an elevated position, and when the shoulder 98 92 the lever 78 becomeseflective to move the slide 58 forwardly until the i'oremost .latch 82 snans over the corresoondino ain l V l a 76 When it is desired to position the parts foroperating upon a right shoe, the operator swings the lever 7 8 in the oppositec irection, and in this'swinging movement of the lever-the front latch-8i, is liiltedfrom the pin 76 and the other latch is released to permit it to engage its pin, and the slide 58 is moved to its limit in the o1 posite direction. It the machine is to operate upon shoes made on crooked lasts the operator adjusts the slides 68. toward each other until the slide 58 is clamped'by the pins 76 in a central position on the, heel carriage, as illustrated in Fig. 7 lilovement of the heel carriage will then adjust the parts of the manner as heretofore.
